It was in Switzerland, over 100 years ago, that herbalists and botanists developed a blend of pure essentials oils that came to be known as Olbas Oil. The name Olbas is an acronym for Oleum Basileum, or “Oil from Basle.” Basle is enviably nestled on the border of Switzerland, Germany and France in the very heart of Europe, and to this day it is a center of pharmaceutical research in Switzerland. Olbas products are now sold worldwide. The official importer for Olbas products is the Penn Herb Company.
